、一枚のリードフレームを一動作で送ることができない
ため、多くの搬送時間を必要としていた。Conventionally, lead frames are transported by inserting pins or claws into one or more holes of the same shape formed at equal intervals on the lead frame, moving the pins or claws a certain amount in the transport direction, and adjusting the position of the lead frame. It was common practice to remove the pin or claw from the hole and place the pin or claw in its original position nine times in preparation for the next transport, but this had the following drawbacks: . In other words, in the above-mentioned method, it is necessary to set the shape and travel distance of the pins, claws, etc. according to the hole shape and hole spacing of the lead door frame, which makes it difficult to transport lead frames of various types and shapes. It is possible to change the transport mechanism when switching lead frames,
The adjustment required a lot of effort and time. In addition, the feed claw blade type can only perform intermittent feeding of one pitch or several pitches at most, and cannot feed one lead frame in one motion, requiring a large amount of conveyance time.

そこで、送９爪刃式に代えて回転するローラーによって
リードフレームを搬送することが考えられるが、この場
合以下のような問題が考えられる。Therefore, it is conceivable to convey the lead frame by a rotating roller instead of the nine-jaw type, but in this case, the following problems may occur.

更する必要が生ずる。In order to eliminate the above-mentioned drawbacks, it is possible to use pins or claws to stop the lead frame at the stop position. It becomes necessary to change the type and position of the pick-up.

さらに、従来装置には以下の欠点があった。すなわち、
作業時にリードフレームのずれ、たわみ、浮き上９を防

よび搬送時にその押さえを解放する機構が必要である。Furthermore, the conventional device had the following drawbacks. That is,
In order to prevent the lead frame from shifting, bending, or floating during operation, a mechanism is required to press and hold the lead frame and a mechanism to release the press during transportation.

従来はそれらの機構が搬送機構と独立していたため、装
置全体の機構が複雑となっていた。Conventionally, these mechanisms were independent of the transport mechanism, making the overall mechanism of the device complex.

ね９でローラ保持杆８を下方に押圧する。In addition, as shown in FIGS. 21 and 3, the horizontal shaft 6 is connected to a bearing 7.
The shaft 6 is rotatably supported on the transport path la, and a roller holding rod 8 is integrally attached to the shaft 6. Attach the elastic roller 3a. Furthermore, a link 1o is pivotally supported on each of the horizontal shafts 6. On the other hand, an air cylinder 1 is placed on one side of the conveyance path 1a.
A connecting rod 11 that is reciprocated in the horizontal direction by a lever 3 is provided, and the connecting rod 11 and the two links 10 and 10 are connected by a link rotation pin 12. Still said horizontal axis 6
A push-up pin 15 is attached to the link 1o, which contacts the backing plate 14 and rotates the backing plate 14 and the horizontal shaft 6 as the link 1o rotates. Further, a leaf spring 9 is attached to the link 10, and this spring 9 presses the roller holding rod 8 downward.

く不要である。In the embodiment, when the lead frame 2 is supplied to the work stage 1, a driving roller 3a placed in a position to sandwich the lead frame and a freely rotating elastic roller 3b
The upper and lower surfaces of the lead frame 2 are clamped and pressed, and the drive roller 3a is driven by the drive motor 5 via the rotation transmission mechanism 4, and the lead frame 2 is moved along the conveyance path without using any feed claws, pins, etc. transported on la. This is the same even when conveying different types of frames, and no adjustment is required at all.

果がある。In addition, since a motor with a large holding torque when stopped, such as a pulse motor, is used as the drive motor 5, the drive roller 3a does not rotate while the motor is stopped, and in addition, since the roller 3b is an elastic body, the frame 2 is placed between the rollers. It is strongly held and there is no risk of slippage, deflection, or lifting. Therefore, there is no need to independently add a frame holding mechanism and a holding release mechanism as in the conventional case, and there is an effect that the structure can be simplified.

できる。Further, a plurality of sensors 16a and 16b are arranged in the middle of the lead frame transport path 1a, and the lead frame position information obtained by these sensors is sent to the control circuit 17 to control the rotation speed of the motor 5. In other words, for example, the frame may be rotated at high speed while the frame is being conveyed, and then rotated at low speed near the stop position to reduce the inertia force, and the frame position once stopped may be detected and the position corrected again. For example, it is possible to accurately stop at a fixed position without using a 9-positioning pin or the like, which has a higher positioning accuracy by τ after transportation.

かつローラ上昇に要する力が小さく動作が軽快になる。In the above embodiment, since the position correction in the direction perpendicular to the feed is performed by the position correction plate 18, it is necessary to raise the elastic roller 3 during correction to eliminate the problem. Note that when the lead frame is being conveyed, as shown in FIG. 3, the roller 3b is pressed against the driving roller 3a by a spring 9 with a certain load. This is because the shaft 6 of the roller holding part
and link 10 are fixed, and roller holding rod 8 and shaft 6 can freely rotate. roller 3b
To raise the connecting rod 11, first use the air cylinder 13 to index the connecting rod 11 to the left in FIG. As the connecting rod 11 moves, the link 10 rotates around the shaft 6, and in order to push up the plate 14 while the pin 15 is fixed to the shaft 6, the shaft 6 and the roller holding rod 8 rotate, as shown in FIG. Like, drive roller 3
A gap is created between a and the elastic roller 3b, and the lead frame 2 located therebetween is free. Of this mechanism, in particular, the spring 9 is connected to the link 10, so when the roller is raised, the force of the spring does not reach the roller holding rod 8, and the roller is attached to the lead frame while it is being conveyed or stopped. Appropriate pressing load is always applied to
In addition, the force required to raise the roller is small, making the operation easier.

とができる。In the above embodiment, as shown in Fig. 1, the upper and lower surfaces of the lead frame were pinched with rollers to provide feed, but as shown in Fig. 5, the left and right edges of the lead frame were pinched with rollers to provide feed. In this case, the gap between both rollers can be expanded using the mechanism shown in FIGS. 2 to 4, and the position of the lead frame can be corrected in the same manner as in the previous embodiment.

のである。In addition to the above, the present invention provides a conveyance roller and its driving mechanism, an elastic roller, a lead frame holding mechanism when the motor is stopped, which is composed of a pulse motor, etc., a mechanism for widening the interval between the rollers, and a position of the lead frame. Because it has a mechanism that detects lead frames and controls the conveyance speed, it is possible to convey different types of frames without adjusting the conveyance mechanism when switching lead frames.Moreover, since it is conveyed by continuous feed rather than intermittent feed, the conveyance speed is It saves time, and because it stops the lead frame by controlling the conveyance speed, its positioning accuracy is high.The rollers also have a function to maintain the lead frame's time in addition to the conveyance function. Therefore, it has the effect of simplifying the mechanism of the entire device.
